F# brings the power of functional-first programming to the .NET Framework, a platform for developing software in the Microsoft Windows ecosystem. If you're a traditional .NET developer used to C# and Visual Basic, discovering F# will be a revelation that will change how you code, and how you think about coding.

In The Book of F#, Microsoft MVP Dave Fancher shares his expertise and teaches you how to wield the power of F# to write succinct, reliable, and predictable code. As you learn to take advantage of features like default immutability, pipelining, type inference, and pattern matching, you'll be amazed at how efficient and elegant your code can be.

Streamline type creation and safety with record types and discriminated unions

Use collection types and modules to handle data sets more effectively

Use pattern matching to decompose complex types and branch your code within a single expression

Make your software more responsive with parallel programming and asynchronous workflows

Harness object orientation to develop rich frameworks and interact with code written in other .NET languages

Use query expressions and type providers to access and manipulate data sets from disparate sources

Break free of that old school of programming. The Book of F# will show you how to unleash the expressiveness of F# to create smarter, leaner code.
